Modify Repmat function to concatenate array
显示 更早的评论
Hello MathWorks community.
I'm trying to concatenate an array of my own "n" times. The thing is that each time each time I concatenate the array, I want to multiply it by 1, 10, 20...
For example, lets say my initial array is [0,1,2,3,4]. And that n =3. Then the output should look like:
out = [0,1,2,3,4,0,10,20,30,40,0,20,40,60,80]
I was wondering if I could use the repmat fucntion in some way to get this don, or is this function only useful for concatanating the exact same array?
Thank's for the help!

V = [0,1,2,3,4];
n = 3;
X = [1,10*(1:n-1)];
Z = kron(X,V)

If you want to understand how repmat works, take a look at the syntax and description in the documentation page: https://www.mathworks.com/help/matlab/ref/repmat.html.
I was able to do this using a loop:
n = 3;
init = [0, 1, 2, 3, 4];
out = init;
for i = 1:n-1
factor = 10*i;
out = horzcat(out, init.*factor);
end
